STORAGE-BATTERY l'omcrron.

Specification of Letters Patent.

Patented Aug. 5, 191 9.

Application filed November 23, 1917. Sci-is! No. 203,474.

To all whom it may concern:

Be it known that I, ALBERT H. LUHRMAN, a citizen ofthe United States of America, and resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Storage- Battery Connections, of which the following is a specification.

An object of my inventionis to produce an improved storage battery connection adapted to eliminate the objectionable loosening of batter terminals due to vibration,

and also the o jectionable seepage of acid from the battery cell.

A further object is to produce an improved storage battery connection adapted to give perfect electrical connection between the connected cells and other elements.

.These and other objects are attained in the battery connection described in the following specification and illustrated in the accompanying drawing in which:

Figure 1 1s a fragmental perspective view of a storage cell having a connect1on, shown fragmentally and in section, attached thereto.

Fig. 2 is a fra mental sectional v1ew upon an enlarged sca e of a battery connection embodying my invention.

y improved battery connection consists of a plate spacing and connecting element .3 having a flan e 4E with a screw threaded portion 5 locate above the flange and an upwardly extending stem 6 pro ecting beyond screw threaded portion 5. A nut 7 is pr0- vided to receive screw threaded portion 5 so that the cover 8 of the battery cell may be clamped between this nut and a washer 9 located upon flan'ge 4. Nut 7 is provided with an upwardly extending couically shaped portion 10 which is provided with an aperture extending through it for the purpose ri' receiving stem 6. Each connector bar 11 of the battery is provided with a conically shaped opening in each of its ends to receive the conically shaped upward extension 10 of nut 7 of adjacent cells.

In connecting a connector bar with a cell bymeans of my improved battery connec-' tion it is necessary first to tighten nut 7 upon the cell cover to cause washer 9 to be compressed between flange 4 and the cover inlprder to prevent seepage of acid'from the ce Connector bar 11 isv then fitted over extension 10 and a blow pipe flame is turned rfect and one which will not loosen Having thus described my invention, what I claim is, V

A. battery connection consisting of a late ,1 holder having a reduced upper end, a ange and a screw-threaded portlon between the reduced end and the flange, a cover resting upon the flange, a nut engaging the screwvthreads clamping the cover against the flange and having an extension fitting the reduced end, and a connector bar having a bore fitting the extension of the nut, the reduced end of the plate holder, the nut and the bar being fused together.

Intestimony whereof, I have hereunto subscribed my name this 21st day of November, 1917.
